Simplifying 0 = x2 + 5x + -1000000 Reorder the terms: 0 = -1000000 + 5x + x2 Solving 0 = -1000000 + 5x + x2 Solving for variable 'x'. Combine like terms: 0 + 1000000 = 1000000 1000000 + -5x + -1x2 = -1000000 + 5x + x2 + 1000000 + -5x + -1x2 Reorder the terms: 1000000 + -5x + -1x2 = -1000000 + 1000000 + 5x + -5x + x2 + -1x2 Combine like terms: -1000000 + 1000000 = 0 1000000 + -5x + -1x2 = 0 + 5x + -5x + x2 + -1x2 1000000 + -5x + -1x2 = 5x + -5x + x2 + -1x2 Combine like terms: 5x + -5x = 0 1000000 + -5x + -1x2 = 0 + x2 + -1x2 1000000 + -5x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 1000000 + -5x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -1000000 + 5x + x2 = 0 Move the constant term to the right: Add '1000000' to each side of the equation. -1000000 + 5x + 1000000 + x2 = 0 + 1000000 Reorder the terms: -1000000 + 1000000 + 5x + x2 = 0 + 1000000 Combine like terms: -1000000 + 1000000 = 0 0 + 5x + x2 = 0 + 1000000 5x + x2 = 0 + 1000000 Combine like terms: 0 + 1000000 = 1000000 5x + x2 = 1000000 The x term is 5x. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5x + 6.25 + x2 = 1000000 + 6.25 Reorder the terms: 6.25 + 5x + x2 = 1000000 + 6.25 Combine like terms: 1000000 + 6.25 = 1000006.25 6.25 + 5x + x2 = 1000006.25 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = 1000006.25 Calculate the square root of the right side: 1000.003124995 Break this problem into two subproblems by setting (x + 2.5) equal to 1000.003124995 and -1000.003124995.Subproblem 1
x + 2.5 = 1000.003124995 Simplifying x + 2.5 = 1000.003124995 Reorder the terms: 2.5 + x = 1000.003124995 Solving 2.5 + x = 1000.003124995 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + x = 1000.003124995 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = 1000.003124995 + -2.5 x = 1000.003124995 + -2.5 Combine like terms: 1000.003124995 + -2.5 = 997.503124995 x = 997.503124995 Simplifying x = 997.503124995Subproblem 2
x + 2.5 = -1000.003124995 Simplifying x + 2.5 = -1000.003124995 Reorder the terms: 2.5 + x = -1000.003124995 Solving 2.5 + x = -1000.003124995 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + x = -1000.003124995 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = -1000.003124995 + -2.5 x = -1000.003124995 + -2.5 Combine like terms: -1000.003124995 + -2.5 = -1002.503124995 x = -1002.503124995 Simplifying x = -1002.503124995Solution
